COMBINED WRENCH AND DRILL.

SPCIFICATlON forming part of Letters Patent N0. 253,549, dated February 14, 1882 Application filed June 7,1881.` (No model.) l

To all 'whom it may concern Be it known that I, JOHN A. MILLER, of St. Charles, Missouri, have made anew and Improved Combined Wrench and Drill, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in which- Figure l is a side elevation of the wrench; Fig. 2, an edge elevation of the wrench; Fig.- 3, an elevation similar to that of Fig. 2, but showing the plate used in fasteningthe wrench proper in the holder turned up; Fig. 4, a side elevation of thewrench, the fastening-plate being upturned; Fig. 5, an elevation of the combined wrench and drill; Fig. 6, a sectional view of the feed device; Fig. 7, a section taken on the line m x of Fig. 5; and Fig. S, a view in perspective, looking toward its outer side, of the pawl.

The same letters denote the same parts.

As ratchet-drills have heretofore been constructed, the screw that takes up the feed is permanently connected with the other parts ofthe mechanism. Neither the drill nor the wrench can be employed separately, and in use the parts are apt to bind so tightly as to interfere with the proper operation of the tool, and to require the feed-screw to be turned back and the drill to be loosened in its bearing. By

` means of the present improvement this objectien is obviated, the feed-screw and holder being so combined with the wrench that the working of either part is not interfered with, and, when desired, the d'rill mechanism can be laid aside and the wrench used as such for the varions purposes a ratchetwrench is ordinarily applied to.

In the drawings, A represents the frame or body of the device, having the wrench B, the wrench-holder C, the ratchet D, the pawl E, and the handle F. The drill G is held in the wrench B, its upper end projecting through the wrench and engaging in the socket h in the feed-screw H. Thelatter is held and engages in a nut', I, which in turn is contained in a frame or holder, J, consisting of the caps j j', connected by the bars jz, and having a square pin, K, extending from the outer head, j, through the nut and into a perforation, h', of corresponding shape within the screw H. The

nut I is perforated at it' to receive a turninglever indicated by the dotted ylines L, Figs'. 6, 7. The nut may be furnished with a ring, i', which, engaging in a corresponding groove in the capj, serves to guide the movement of the nut more steadily in the holder J. The nut I is made to turn freely upon the pin K, the perforation in the nut being of sufficient size therefor. The pin prevents the screw H from rotating with the nut, and as the latter is turned the screw is moved longitudinally on the pin. The holder J in use is supported at its outer end in the usual manner, and as the drill-point is advanced by the wrench the screw His kept against the head ofthe drill by suitably working the nut l with the lever L. Although the holder J, the wrench A, and drill G are combined to effect the drilling, the workin g of either the wrench or the drill-holder is free of the strains imposed upon the other,and to use the wrench by itself the drill-holder has merely to be laid aside.

Theimprovement further relates to the means used in fastening the wrench proper, B, in the holder C. This is accomplished by' means of the plate M, which is pi-voted to the handle F at m, and extends thence over upon the ratchet D, being at that end shaped to encircle the projection b of the wrench B, but preferably not to Wholly encircle the projection b, leaving a space, b', upon the ratchet D, to enable the operator to clasp the ratchet with his thumb and keep the ratchet from turning back as the wrench-handleis turned back for another movement of the wrench, as the nut or other thing being turned by the wrench is apt, when loose, to follow the movement of the handle. The plate M is, however, extended far enough for its arms m m to bear upon the Wrench at opposite sides thereof, and upon the side of the ratchet, and hold the Wrench evenly in the holder, and but for the arms m m bearing against the side of the ratchet the wrench, when turned with the ratchet side downward, would drop out of the holder C. The plate is furnished with a tongue, m2, which tits into a recess, m3, in the handle F, and by means of a screw, m4, passing into the handle F, and the perforation m5 in the tongue, the plate can be fastened down upon the Wrench. To detach vthe wrench B from the holder C the screw m4 IOO is disengaged from the tongue maud the plate M turned up, as in Figs. 3 and 4, leaving the Wrench free to be Withdrawn from the holder C. AThe pawl E, upon its outer side, is furnished with aprojection e, which engages loosely in a recess,m"`, in the plate M, and operates to hold the paWl in its seat when the tooth of the pawl is Withdrawn from the ratchet D. This l ind to be better than peii'orating the pawl and hanging it on a pin, as in constructions previously patented.

I claiml. The combination of the wrench B, drill G, screw H, and holder J, having the heads jj', barsjz, pin K, and perforated nut4 I, said 15 holder and screw being detachable from the drill and wrench, substantially as described.

2. The combination of the handle F, plate M, having the perforated tongue m2, the recess m6, and arms m m, the paWl E, having the zo projection e, the screw m4, the holder G,Wrench B, and ratchet C, substantially as described.
